Nearly 200 years ago, Earth’s magnetic field weakened rapidly, and the weakening may be due to a reversal of the poles, but not according to a new study.
The Earth’s magnetic field protects it from particle radiation from space and the sun. There is an area over the South Atlantic Ocean where the magnetic field is very weak, so satellite electronics passing through that area must be turned off to avoid being hit. SVT.
Some see this deviation as the beginning of the reversal of the poles. If the north and south poles switch places, it wouldn’t hurt us, it has happened many times in Earth’s history. However, the reversal can take more than a thousand years and then the magnetic field weakens, which can have serious consequences.
in New study Scientists say they believe the weakness over the Atlantic will dissipate without serious consequences. They have made reconstructions that indicate that the weakness will disappear in the next 100 years.
“We have used geological and archaeological materials that provide information on the strength and direction of the magnetic field. During our reconstruction over the past 9,000 years, we have found similar types of anomalies on Earth,” says study co-author Andreas NilssonGeologist and university lecturer at Lund SVT.
